Apr 24, 2017 · Copper most commonly exists in chalcopyrite and sulphide ores. Silie, sulfate and carbonate ores also contain copper. The low percentage of copper in these ores makes it necessary to concentrate them before electrolysis, according to Chemguide.
How much metal does the ore contain? « World Ocean Review
In most cases copper ores contain between 0.6 and 1 per cent of copper. Consequently one tonne of ore generates a maximum 6 to 10 kilograms of copper. In the case of platinum the yield is much lower: 1 tonne of ore usually contains between 3 and 6 grams of platinum. Nonetheless it is still worthwhile mining because the platinum price is high.
Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silie minerals or oxide minerals for which there is often no value. In some cases, tailings have been retreated to recover lost value as the technology for recovering copper has improved.

Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silie minerals or oxide minerals for which there is often no value. The average grade of copper ores in the 21st century is below 0.6% copper, with a
BotEC: Percentage of Copper in Ore Activity Collection
Question. Suppose that you are building a new house. It will take about 90 kg (198 pounds) of copper to do the electrical wiring. In order to get the copper in the first place, someone needs to mine solid rock that contains copper, extract the copper minerals, throw away the waste rock, and smelt the copper minerals to produce copper metal.
Apr 23, 2011 · Both ore types can be economically mined, however, the most common source of copper ore is the sulfide ore mineral chalcopyrite, which accounts for about 50 percent of copper production.
Top Copper Producing Countries In The World worldatlas
Apr 25, 2017 · Mining operations extract copper from the ground via open pit mines. Once the coppercontaining earth is extracted, the extract is ground to fine ore and put through a froth flotation process. This process combines the ore with water and a collector chemical that makes copper hydrophobic (a condition which repels water).
